%X in this paper, the effect of the detonation energy of explosive charges as a method to reduce residual stresses in the heat affected zone of welded joints was studied. a comparative analysis of two alternatives for the positioning of the explosive charge is made: one of linear form and the other sinusoidal. the results obtained before and after the treatment demonstrate the effectiveness of the method and that in both cases a decrease in residual stress is obtained, with values which range between 50 and 60%, allowing us to affirm that both alternatives offer a possible solution to extend the working life of the welded joints.
